tamiya stuff has always been nuts. put that back in the box and stick in a closet and it will apreciate faster than the real thing. lol.
I built a ton of plastic models and the Tamiya stuff is the best. I have 3 of their bike models on my closet shelf just waiting for me to ever have time. I’ll probably spend 100+ hrs on one if past performance is a clue. I built a 1/32 F4 for my father in law I could say confidently I spent 250+ hours on.
Way back when I built an RC30 which I wanted to be a race bike so I went so far as to leave off the mirrors and fenders and ordered some slicks from some other model right from Tamiya. I still have it, but I didn't protect it well and dust will never come off, so get a display box if it turns out.
